Free Credit card to BOB Credit card bill repayment (I think Kotak credit card will also work but not sure):
Trick is shared by @Harry1
Download through refer link for New Payzapp app.
Load money using any credit card on your new Payzapp wallet and pay to your BOB Credit card bill repayment via Payzapp wallet balance.
Note - Only BOB credit card is working and you can use only for the amount that was in last bill. Bill amount can't be edited.
You can remove biller and add biller multiple times to perform multiple transactions. No idea if there is 1Lakh or 2 Lakh limit for payzapp wallet full kyc.
I think BOB CC support via BBPS system that's why working. Kotak CC also added on BBPS, anyone tried then comment below.
